its way different than the video games. you can only pass on the left and if you see a faster car behind you put your right blinker on and move to the right to let them pass. check your mirrors every few seconds. watch the safety vids on that nurburgring website. to buy things in the store front for the gp track you need a ring card and put money on it. to buy laps for 26 euros iirc u can use euros to buy them at the nordschliefe entrance ticket booth.
on that same website is locations for spectator spots. my fav spots are by the village of adenau by the corner briedscheid, and then the corner brunnchen.
i dropped my bike t Adenau Forst lol
